ON WORLD ASTRONOMY DAY, HOW ABOUT LOOKING UP? The Citroen C3 is the perfect car to associate with that date, because of its unique Zenith windshield. We decided to use Instagram in a different way. We used its layout as a large mosaic to represent a greatness of the vision of the Zenith windshield of the C3. For this, the mosaic goes from an inner view of the C3 to the extratosphere!
